The crew fit Pirelli with his new foot, a process that took almost three hours, with many trips back to the shop to tweak and perfect the prosthetic.

Finally, it was fastened into place and Pirelli took his first steps, holding his new foot off the ground at first. But within minutes, he was walking with confidence, his back leg landing on the practice runway.

Pirelli will wear this foot for a few weeks before he is fitted with the final version before Christmas.
